Hi all, 

Complete noob here and slowly getting my head around setting up my UNRAID server. 

I have just added a new SAS drive to my array and copied a bunch of videos to it last night. I noticed the HDD was getting a bit warmer than I would like (44-45deg), so this morning, after the data was copied, I shut down the server and installed a couple more case fans. Note - the HDD didn't overheat overnight as I directed an external fan on it while the copy finished and it came down to 30ish degrees.  

When I restarted UNRAID after the fan install, I have the following warning: UNMOUNTABLE: WRONG OR NO FILE SYSTEM XFS next to the newly installed drive. 

I have looked around the forums and it seems there are a few causes - I'm not so much worried about the data (I haven't deleted the original source yet), but I am concerned later down the track, I will have similar issues because I'm not quite sure what went wrong. My main priority is just to get the array back up and working quickly and preventing any further issues once I have more data on it. 

I have completed a disk check and attached that and the diagnostics. Apologies the diagnostics were saved after a restart because it did not dawn on me to grab the diagnostics before I try fix it with a reboot.

As always, thanks in advance for your help

Check filesystem on disk2.

Thanks, I have done this - afterwards all the data was lost but the drive mountable again. 

I'm not so worried about the data on the drive - just not sure what I did wrong to prevent it from happening later down the track 

Difficult to say what caused it since the problem was already there after boot, but it was a strange error, and it was making xfs crash which is not normal.

Cheers, 
 

Thanks again for your help
